Solution Overview

Problem

Current mechanical ventilator systems for patients with chronic respiratory insufficiency or failure face challenges in remote monitoring, as they often lack timely adjustments to changing patient needs, leading to inappropriate response times and potential respiratory complications when caregivers are absent or unable to intervene.

Innovation Solution

A programmable mechanical ventilator system that allows clinicians to automatically update ventilation settings based on real-time biometric data, targeting predetermined measures of normality without relying on diagnostic algorithms, ensuring adjustments are within approved ranges and transparently following physician-directed interventions.

AI summary

A system and method are provided for dynamically controlling operation of a mechanical ventilator for automatic targeting of a monitored parameter. A ventilator prescription includes an initial ventilator configuration, a prescribed target biometric value, comparator formulae for comparing a current condition value to the prescribed target biometric value, and modification formulae for generating modification parameters to modify the current configuration of the system. The ventilator system operates according to the initial configuration, continuously monitors patient biometric sensors and system biomarker calculators, periodically determines a current condition value, and compares the current condition value to the target biometric value. If the current condition value does not meet the target biometric value, the system generates modification parameters to modify the current configuration of the system and automatically reconfigures the current configuration according to the modification parameters to meet the prescribed target value.
